It is important to note that CalMAN is creating the LUT and Prisma is the box where the
LUT gets stored and then is inserted in line between the source and the display.
5.
During creation of the LUT there are two main parts - measuring the display with your
colorimeter and then with those measurements creating a LUT file (.3dl) to be placed in the
Prisma. The Prisma is used by CalMAN as a generator during this phase of LUT creation.
The Steps Are:
1) CalMAN ColorCube Workflow
2) Connect to your Meter
3) Connect Prisma as the Generator – Prisma has built-in RGB triplet generator.
4) Connect SpectraCal Cube LUT as your Display
5) IMPORTANT NOTE: On the Generator Tab in CalMAN there are unique settings for the Prisma -
one very important setting is a small box call Bypass 3D LUT. The default for this setting is checked
- meaning the LUT in the Prisma is not in the signal path. When creating LUTs you must leave this
box checked - so you don't write a LUT on top of another LUT. When you want to see how good of
a LUT CalMAN created you would uncheck this box once the LUT file is loaded in the Prisma and
then run a saturation sweep in post calibration.
6) On the 3D LUT step in CalMAN pressing the Auto-Cal button will bring up the page below:
7) In the middle of the page is Cube Generator Output - This is where we set up the attributes for
the LUT as follows:
File Format = 3DL
Output Cube Size = 17 Points
Bit Depth = 12
